CSRD vs ESRS: What Is the Difference?

The distinction matters because a technically good ESRS disclosure cannot cure a wrong legal scope conclusion, and a correct conclusion that a company is in scope does not tell the reporting team which datapoints, boundaries, reliefs and presentation rules apply. Compliance requires both routes to be controlled and then connected.

CSRD is shorthand for the Corporate Sustainability Reporting Directive, Directive (EU) 2022/2464. It did not create a self-contained reporting code separate from existing company law. Instead, it amended Directive 2013/34/EU, commonly called the Accounting Directive, as well as related audit and transparency legislation. The legal duties to include sustainability information in the management report, obtain an assurance opinion and prepare information in an electronic format therefore sit within that wider legislative architecture.

Directive (EU) 2026/470, known as Omnibus I, amended the framework again. It narrowed the mandatory reporting population, removed the listed-SME route, introduced new value-chain protections and instructed the Commission to simplify the ESRS. It entered into force on 18 March 2026, but Articles 1 to 3 must be transposed by Member States by 19 March 2027. A directive binds Member States as to the result to be achieved; the company-facing obligation normally needs to be read in the domestic implementing law.

Article 29b of the Accounting Directive empowers the European Commission to adopt European Sustainability Reporting Standards. The first set was adopted as Commission Delegated Regulation (EU) 2023/2772. A targeted “Quick Fix” amendment, Delegated Regulation (EU) 2025/1416, extended selected phase-in reliefs for undertakings already reporting. Revised ESRS were adopted by the Commission on 3 July 2026 through act C(2026) 5010, but at the review date they had not yet entered into force because scrutiny and Official Journal publication were still outstanding.

Unlike a directive, an EU regulation is directly applicable once it is in force. Member States do not rewrite the ESRS into national standards. However, the regulation applies to undertakings that are required by the transposed Accounting Directive rules to report, and the national law may affect scope, exemptions, filing, enforcement, assurance-provider eligibility and other procedural matters.

For a specific company, the enforceable answer depends on the law of the relevant Member State or States. A parent may have to consider the jurisdiction of incorporation, the rules governing the management report, issuer home-Member-State requirements, subsidiary exemptions, filing law and auditor or independent assurance-provider rules. Omnibus I’s new thresholds and transition provisions must be brought into national law by the deadline, and Member States may use certain derogations - including a potential exemption for below-new-threshold wave-one entities for financial years beginning in 2025 and 2026.

At EU Directive level, Omnibus I targets the main individual and consolidated reporting duty for financial years beginning on or after 1 January 2027 at undertakings or groups that exceed both EUR 450 million net turnover and an average of 1,000 employees during the financial year. It also adjusts issuer rules, removes listed SMEs from the regime, applies the reduced scope logic to qualifying credit institutions and insurance undertakings, and revises the third-country route.

The third-country route uses a different test. The non-EU parent must have generated more than EUR 450 million net turnover in the Union for each of the last two consecutive financial years, together with an EU subsidiary exceeding EUR 200 million net turnover in the preceding year, or - where there is no qualifying subsidiary - an EU branch exceeding EUR 200 million. These thresholds answer whether a report is required under Article 40a; they do not tell the group which standard version or transition option to use.

Identify the relevant legal entities, parent, issuer and reporting jurisdictions.

Calculate individual and consolidated thresholds using documented definitions and periods.

Check national transposition, derogations, subsidiary exemptions and third-country provisions.

Determine the applicable ESRS delegated regulation and any transition choice.

Perform double materiality and map material information to the applicable ESRS requirements.

Prepare the statement in the management report and design assurance, governance and digital-format controls.

Reconfirm the legal and standards analysis immediately before board approval and filing.

This wording separates the national legal obligation from the ESRS preparation basis. It must not be used without confirming the exact domestic citation, reporting level, standard version, exemption position and approval facts.
